Wooden barrels are cylindrical containers traditionally made from staves of wood, typically oak. They are commonly used for aging and storing liquids, such as wine, whiskey, and beer. The wood imparts unique flavors to the contents, enhancing their taste over time. Barrels are often sealed with a wooden or metal lid, known as a bung, to prevent leakage. The construction of wooden barrels involves careful craftsmanship, where the staves are shaped and fitted together without the use of nails. This method allows the barrel to expand and contract with temperature changes, maintaining its integrity. Barrels can vary in size, with some holding just a few gallons and others containing hundreds.
